The Mobil Glygoyle brand of lubricants is recognised ａnd appreciated around the world for its innovation ａnd outstanding performance. The molecular designed polyalkyleneglycol synthetic products have been specially chosen for use in Mobil Glygoyle 11, 22, ａnd 30 ａnd demonstrate the continuing commitment to using advanced technology to provide outstanding product performance. A key factor in the development of Mobil Glygoyle 11, 22, ａnd 30 were the close contacts between our scientists ａnd application specialists with key OEMs to ensure that our product offerings will provide exceptional performance in the continually evolving industrial equipment designs.

Mobil Glygoyle products were primarily designed to meet the critical high temperature needs of a variety of industrial equipment where mineral-based ａnd other synthetic products were not able to perform satisfactorily. Additional features such as low friction ａnd traction, gas absorption properties resulted in even broader industrial application opportunities. Mobil Glygoyle 11, 22, ａnd 30 lubricants offer the following features ａnd potential benefits:

Mobil Glygoyle lubricants are recommended for the most severe conditions in all types of plain ａnd anti-friction bearings ａnd industrial enclosed gears up to a bulk oil temperature of 200º C. Specific applications include:

- Severe plastic calendar operations

- High temperature paper machine bearings

- Industrial enclosed gears – spur, bevel ａnd worm gearing

- Reciprocating ａnd rotary air, natural gas, CO2 ａnd other process gasses

Application notesPolyalkyleneglycol (PAG) based lubricants have some inherent excellent lubrication properties imparted by the PAG base oil. However, PAG based lubricants do have limitations with respect to compatibility with seal ａnd coating materials, some varieties of light metal alloys ａnd other lubricants.  Before applying any PAG lubricant, contact the original equipment manufacturer for specific advice on the application.

Compatibility with other lubricantsMobil Glygoyle 11, 22, ａnd 30 are not compatible with mineral oils ａnd most other synthetic lubricants.  Additionally, depending on the specific type of PAG base fluid, they may not be compatible with other PAG type lubricants. (e. g. Mobil Glygoyle 11, 22, 30 ａnd Mobil Glygoyle ISO VG Series are not miscible)Mobil Glygoyle 11, 22, ａnd 30 are not generally recommended for use in systems previously filled with mineral oils or PAO based synthetic lubricants.  It is further recommended to check compatibility when topping up or replacing existing PAG fillings with Mobil Glygoyle products, generally the preference is to avoid mixtures by draining, flushing ａnd refilling.When changing from mineral oil or other synthetic products to Mobil Glygoyle products, it is crtical to clean the system thoroughly ａnd flush with suitable fluids prior to conversion. For further details please contact your ExxonMobil representative.

WaterMobil Glygoyle 11, 22, ａnd 30, along with all PAG based lubricants, are hygroscopic ａnd absorb more water than mineral oils or synthetic hydrocarbons before. Therefore extra care should be taken not to expose PAG oils to excessive moisture.  Due to their inherent high specific gravity, water does not ｄrop to the bottom of reservoirs, but stays on top of the lubricant.

Seal compatibilityPAG based lubricants are not compatible with most standard seal materials used for mineral oils or synthetic hydrocarbons. Incompatible materials are likely to shrink or swell, thus causing severe leakage or seizure of the seal. When converting from mineral oil or synthetic hydrocarbons to Mobil Glygoyle 11, 22, or 30, seal compatibility must be considered.. FKM ａnd VMQ are normally suitable for use with PAG.  NBR materials may be used but have restricted temperature range.    In all cases, operating conditions ａnd the variability of elastomer properties from different manufactures should be considered.  For best results, consult the equipment supplier or seal manufacturer for specific recommendations. 

Light Metal AlloysMobil Glygoyle 11, 22, ａnd 30 ａnd PAG lubricants are well suited for gear applications with ferrous ａnd most non ferrous materials.  However, Mobil Glygoyle products ａnd PAG lubricants are not recommended for use with light metal alloys containing Aluminum or Magnesium.  PAG lubricants can lead to increased wear when used with light metal alloys of this nature.  Please consult the original equipment manufacturer for additional information.   

Other MaterialsPaints, coatings, ａnd some plastics are not suitable for use with PAG lubricants. In general two component paints (reactive paints, epoxy resins) are suitable for use for interior coatings in contact with the lubricant.  Otherwise, interiors in contact with the lubricant should be left uncoated.  Materials used for oil level gages, inspection doors etc., should preferably be made of natural glass or polyamide materials. Other transparent plastics, e.g. Plexiglas, may deteriorate ａnd crack under stress.
